^c Model 3: Odds ratios for NRS 4–10 was assessed against a reference of NRS 0 or no pain
^d Model 4: Odds ratios for NRS 7–10 was assessed against a reference of NRS 0 or no pain
^e AUDIT scores are calculated as the sum of 10 items, and were categorized into Zone I (0–7), Zone II (8–15), Zone III (16–19), and Zone IV (20+)
